Answer
about 270
Work Step by Step
You have y=100 $\times$ $1.22^{x}$.The population is growing and you have to find the numbers of frogs in 5 years:
y=100 $\times$ $1.22^{x}$
y=100 $\times$ $1.22^{5}$
y=270.27 -since you cant have half a frog, the population would be about 270 frogs-
y$\approx$270
There will be about 270 frogs in 5 years.
